Synopsis

Build agents that are dependable, testable, and ready for real work. This practical guide presents AI agent engineering as a disciplined software practice, connecting model behavior with tools, data, state, security, and measurable outcomes.

Rather than treating an agent as a single prompt, the book shows how to design a complete system that can interpret intent, make controlled decisions, use external capabilities, recover from failure, and verify its results. Clear explanations are paired with implementation patterns and practical examples, so readers can move from concepts to production-minded designs.

Inside, you will learn how to:

• Define reliable agent boundaries: distinguish agents from workflows, establish execution limits, and convert user requests into observable success criteria.
• Shape model behavior: select models based on reasoning needs, cost, and latency, then combine instructions, context, schemas, and validation for consistent outputs.
• Control multi-step execution: apply observe, decide, act, and verify loops with termination rules, progress checks, ambiguity handling, and safe recovery from failed attempts.
• Connect tools responsibly: create precise contracts, construct and validate arguments, interpret results, and manage authentication, permissions, retries, timeouts, idempotency, and rate limits.
• Ground answers in knowledge: design ingestion and metadata pipelines, combine vector and hybrid retrieval, select evidence, track citations, and reduce unsupported claims.
• Manage memory and context: separate working, episodic, and semantic memory while establishing policies for writing, retrieval, expiration, privacy, consent, and deletion.
• Plan complex work: decompose goals into dependent tasks, coordinate parallel work, respect resource limits, and replan when conditions change.
• Preserve progress: use checkpoints, event logs, state transitions, conflict handling, and durable execution patterns for long-running operations.
• Coordinate multiple agents: compare supervisor, pipeline, debate, and blackboard architectures, with clear roles, handoffs, and communication contracts.
• Defend high-impact systems: address prompt injection, data exfiltration, tool misuse, input and output controls, threat modeling, and human approval gates.
• Measure and improve quality: build unit tests, scenario suites, regression checks, adversarial cases, traces, metrics, and useful failure taxonomies.
• Operate in production: plan deployments, configuration, cost and latency controls, versioning, incident response, rollbacks, and continuous improvement.

Designed for practical application

Each chapter develops a core engineering idea and concludes with a realistic example, including research assistants, document extraction, troubleshooting, calendar and email actions, policy question answering, support memory, market analysis, claims processing, financial tools, customer service, and document processing.

AI Agent Engineering Fundamentals is a focused reference for developers, architects, technical leads, and product teams who want to create agentic applications that are capable without being reckless, flexible without becoming unpredictable, and useful under real operational constraints.
